Lab #6: Using Mask Test

With mask testing you can set up a pass/fail test criteria for automatically
testing waveforms to see if they conform to specific wave shapes. In this
lab we will test a digital signal that includes an infrequent glitch. With
InfiniiVision's hardware- based mask testing capability, we will be able to
test up to 280,000 waveforms per second and gain insight into the
statistical occurrences of this particular glitch. To enable Mask Testing,
your oscilloscope must have the mask test option installed (Option MASK).
You can verify the installed options on your oscilloscope at [Help] > About
Oscilloscope.

3000 X-Series Oscilloscopes Advanced Training Guide
Connect the channel- 1 probe to the Demo 1 terminal and ground.
Press [Default Setup] on the scope's front panel.
Press [Help]; then press the Training Signals softkey.
Using the Entry knob, select the Clock with Infrequent Glitch signal; then
press the Output softkey to turn it on.
Set channel- 1 to 500 mV/div and position/offset to 1.0 V.
Push the Trigger Level knob to set the trigger level at 50%.
Set the timebase to 20 ns/div.
Set the waveform intensity to 100% by first pressing the [Intensity]
button; then turn the Entry knob.
